,V Application filed July 8, 1907. Serial No. 382,791.

Patented .Tune 23, 1908.

To all' 'whom tt 'may concern:

Be it known that I, EDMoND FOURNIER, a subject of the King of GreatBritain, residing at St.` Hyacinthe, county of St.. Hyacinthe,

in the Province of Quebec, Canada, have invented certain new and usefulImprovements'in Loose-Leaf Binders and I do hereby declare that thefollowingk is a full, clear, and exact description of the invention,such as will enable others skilledin the art to f:which it appertains tomake and use the same.

My invention relates to loose-leaf binders of theV general typecomprising two covers adapted tocontain between thema plurality ofrecord sheets, papers or the like, means for moving these covers bodilytoward or from each other in order to securely clam-p the papers heldtherebetween regardless of '20 .theirenumber and devices for guiding thecovers in their movements.

The present invention is designed to construct a binder of the generalty e above in which all tendency toward bin 'ng of the guiding parts iscom letely overcome and to produce an article of this class in which theparts may be locked in their ad'usted positions and to securely guardthe ook against persons who may wish to tamper with the same to gainaccess to papers in the binder.

Broadly speaking my invention comprises in combination with the coverscommon to devices of this class and guide rods and their coperatingguide tubes connected 'to the late and connections between the backpllate and covers for guiding the covers as they are moved and a guardplate adapted to be moved over the key-hole through which the key isinserted to operate the rods whereby the covers are moved in one or theother direction.

As heretofore constructed binders of this general type have aHorded nosubstantial protection against persons wrongfully open- This was due tothe fact that the slot or key-hole in the end of the o erating shaft waseasily accessible and any key or piece of metal inserted therein wouldoperate the actuating rod and so release the covers.

One of the prime objects of the present invention is to completelyovercome this serious objection.

Another object is to prevent binding between the guide rods and theirtubes.

In order to more clearly understand the construction and operation ofthedevice ref-- erence should be had to the accompanying drawings formingpart of this present application in which similar reference characters`designate like parts in' ally of the several views.`

Figure 1 is a front plan. view of the deviceA showing the back plate inelevation. Fig. 2y is a plan view ofthe end' plate or cap con-tainingthe guard plate and its actuatingmeans'. Fig. 3 is a longitudinalsection through Fig. 2 looking from the opposite side tov that shown inFig. 2 land showing the guard plate .in inoperative position. Fig. 4 is.a view similar to 3 with the guard platev in o Aerative position. Fig. 5is a section on ne l 5 5.- of Fig. 2. Fig. l6 is a perspective indetailV showing the connecting pin in platey 1. Flg. 7 is a perspectiveof the'end or cap platek pposite. to the one:A containing the guard o pate mechanism.

Referring to the drawings in detail, 1I repi resents. suitable covers ofa form common to all devices ot this. genera-l' ty e.. Connected to thecovers l any suitable manner are bars 2 or equivalent structures of anywell known form carrying the usual guide rods or` pins 3 and theirrespective coperating guide tubes 4.

In order to prevent twisting lof the covers` and consequent bindingbetween the members 3 and 4 I have provided a back late 5 provided witha fastening pin or stu 25 by which it is held to one end of the binderback. This plate as clearly shown in Fig. 1 is placed between the rodand tube connections and the back of the binder, the pin 25 engaging asuitable recess in the binder back.

In order that plate 5 may act las a guide I have provided t e same wlthsuitable guide slots 6 ada ted to receive ins 7 attached to the lower as or inturne edges of the covers 1 all as cllearly shown in Fig. 1. Itfollows that as the covers are moved in either direction, the late5being stationary pins 7 will ride in s ots 6 and the covers will bemaintained in perfect perpendicularity and vconsequent bindin betweenthe' guide rods and guide tubes w be obviated.

To opposite ends of the back of the binder are attached respectively endcaps 8 and 9 respectively provided with recessed Han es 21 adapted toreceive and hold a suita le binding 22, see Fig. 7.

The end cap 9 has slidably mounted therein a guard plate 10 providedwith an opening 13 adapted to register with a similar opening 14 throughthe outer face of the cap 9 through which latter o ening a key or otherdevice may be asse to o erate the well known form of ey operateactuating rod whereby the covers are moved. Guide plate 10 has attachedthereto a pin 11 which projects through a slot 12 in the end cap 9 andis provided with a suitable head by which it may be grasped and movedtoward the right, Fig. 2, to thereby register openings 13 and 14 andallow insertion of a key for operating the actuating rod.

The plate 9 is held in its inoperative position with the o enings 13 and14- in register as above by a og 15 pivoted at 16 adjacent said plateand provided with a notched arm lying in the path of movement of theplate. This dog is normally held elevated by the spring 18 as clearlyshown in Figs. 3 and 4. The notched arm of dog 415 engages stud 17 onplate 10 and so holds the plate inoperative when it has been moved tothis position by lthe pin 11.

In order to free the guard plate and allow it to be moved into operativeposition a key is` inserted in the opening 19 and the dog 15 turned todisengage its notched arm from stud 17, the knob on the end of in 11 isthen grasped and the plate 10 move to operative position as shown inFigs. 2 and 4 and so eld by the arm of dog 15 which has now been forcedupward into engagement with the shoulder 23 of plate 10, see Fig. 4.

Having now fully described the construction and operation of my device,what I claim and desire to secure by Letters Patent is:-

1. In a loose leaf binder, a key o erated actuating rod, a sliding guardplate ying in the path of insertion of a key for operating saidactuating rod, means for slidlng said guard plate, a stud on said guardplate7 and a shoulder on said guard plate and a s ringactuated pawlprovided with a notche arm, the notch of which is adapted to receive theaforesaid stud to hold the guard plate in inoperative position, whereasthe end of the arm of said pawl is'adapted to engage the guard latebeneath the shoulder thereon and to old it in operative position.

2. In a loose leaf binder, a key o erated actuating rod, a sliding guardplate ying in the path of insertion of a key for operating saidactuating rod, means for sliding said guard plate, a stud on said guardplate, and a shoulder on said guard plate, a spring-actuated pawlprovided with a notched arm, the notch of which is ada ted to receivethe aforesaid stud to hold t e guard plate in inoperative position,whereas the end of the arm of said pawl is adapted to engage the guardplate beneath the shoulder thereon and to hold it in operative position,and a second arm on said lpawl adapted to be engaged by a key by whicsaid pawl may be actuated.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.

EDMOND FOURNIER.
